    Are you certain that port is not open. Try running active ports on it and see what is occurring. You can download it here:

    Could we get a little more info?  Is your application a 'server' which clients connect to or is it a 'client' that connects out to another machine somewhere?  If it is a 'server' you can use     netstat -an    to find out if your application is listening.  Here is an example pulled from my machine.  It shows that I am listening for connections on port 135:

    C:\>netstat -an

    Active Connections

      Proto  Local Address          Foreign Address        State
      TCP                LISTENING

    Are you using a software based firewall on your 2003 server?  If not, it may be your LAN firewall that is blocking your connection.
